I said it was probably DDR because as far as I know, only DDR is dual channel. PC400 could also have been referring to PC400 SDRAM, which is a lot older and outdated, but the dual channel part implied not. And I said "DDR 400MHz" is the same as "PC3200". So... not really sure what I need to explain, since I basically said the exact thing you did

Just razzen ya, SDram would be PC66, PC100 and PC133. And RDram on 820 chips sets was dual channel as PC600 and PC800, quad on the 850 and 860 and added PC1066.
